Tripolar Overvoltage Protection for Network Interfaces LT3021 SO-08 Description The LT3021 is a low capacitance transient surge arrestor designed for protection of high debit rate communication network. Its low capacitance avoids distorsion of the signal as it has been designed for T1/E1 and Ethernet networks. Features u u u u Tripolar crowbar protection Low capacitance Repetitive peak pulse current: IPP=30A (10/1000μs) Low holding current: IH=30mA Functional Diagram Applications Dedicated to data line protection, this device provides a tripolar protection function. It ensure the same protection capability with the same breakdown voltage in both common and differential modes. Electrical Parameters Symbol Fig1.
